Benefits of technology
The solution effectively prevents accidental button activations, ensuring intended actions are taken while providing user feedback through color changes, enhancing user experience and reducing errors.
Problems solved by technology
Usually, mechanical buttons of electronic devices, for example, buttons of mobile phones, can be actuated by a press, which may result in accidental activation or deactivation.
For example, if a dial button of a mobile phone is pressed by accident, an unwanted phone call may be placed, which may bring trouble to communication parties of the unwanted phone call.

Embodiment Construction
[0011]Referring to FIG. 1, an electronic device 100 in accordance with an exemplary embodiment is shown. The electronic device 100 may be a mobile phone, a PDA, or the like. The electronic device 100 includes a housing 10, a display 20, and a rotatable keypad 30. The display 20 and the keypad 30 are received in the housing 10. The display 20 is configured to display visual information. The keypad 30 can be rotated clockwise or counterclockwise when an external force is exerted on, and can return to its original state when the keypad 30 is released. In this embodiment, the keypad 30 is substantially annular.
[0012]The keypad 30 includes a plurality of buttons 31. In this embodiment, ten numerical buttons 31 from 0 to 9 are shown. The buttons 31 can vary according to need.
[0013]The electronic device 100 further includes a first conductive surface 40 (see FIG. 2) and a second conductive surface 50 (see FIG. 3). The first conductive surface 40 is attached to the bottom of the keypad 30 a...

A method for controlling an electronic device is provided. The electronic device includes a housing, a keypad, a first conductive surface, and a second conductive surface. The keypad is rotatable and includes buttons. The first conductive surface is attached to the bottom of the keypad, rotatable with the keypad, and includes first contact portions. The second conductive surface is fixed in the housing, arranged below the first conductive surface, spaced apart from the first conductive surface, and includes second contact portions. The method includes determining which of the buttons is pressed. Determining whether an activation signal is received, wherein when the first contact portion contacts one of the second contact portions which shape is the same as the first contact portion, the activation signal is generated. Determining the pressed button is activated if the activation signal is received, and executing a function corresponding to the activated button.
Description
BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to electronic devices and methods thereof and, particularly, to an electronic device having a rotatable keypad and a method for controlling the electronic device.[0003]2. Description of Related Art[0004]Usually, mechanical buttons of electronic devices, for example, buttons of mobile phones, can be actuated by a press, which may result in accidental activation or deactivation. For example, if a dial button of a mobile phone is pressed by accident, an unwanted phone call may be placed, which may bring trouble to communication parties of the unwanted phone call.BRIEF DESCRIPTION OF THE DRAWINGS[0005]The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of an electronic device with a rotatable keypad and method for controlling the electronic device. Moreover, in the drawings, like reference numerals designate corresponding parts ...
